Treating dysfunctional cardiac tissue
First Claim
1. A system for treating a heart of a patient via a percutaneous heart access comprising:
- a first catheter that is configured for advancing a distal end of the first catheter through a femoral vein or an internal jugular vein, through a vena cavae and a right atrium of the heart, and through a tricuspid value into a right ventricle of the heart;
an introducer that is disposed within a lumen of the first catheter and that is advanceable from the distal end of the first catheter when the distal end of the first catheter is positioned adjacent a septum of the heart, the introducer being configured to perforate the septum subsequent to advancement of the introducer from the distal end of the first catheter;
a guidewire that is disposed within the lumen of the first catheter and that is advanceable from the distal end of the first catheter through the perforation in the septum so that a distal end of the guidewire is positioned within a left ventricle of the heart, the guidewire and first catheter being configured so that the distal end of the first catheter is advanceable over the guidewire and through the perforation in the septum so that the distal end of the first catheter is positionable within the left ventricle adjacent an anterior or lateral wall of the left ventricle, the introducer being further configured to perforate the anterior or lateral wall of the left ventricle when the first catheter is positioned adjacent thereto, and the guidewire being advanceable from the distal end of the first catheter through the perforation in the anterior or lateral wall of the left ventricle so that the distal end of the guidewire is positioned external to the heart;
a first anchor that is deliverable percutaneously through the lumen of the first catheter and that is deliverable from the first catheter through the perforation in the anterior or lateral wall of the left ventricle, the first anchor being configured for positioning on an exterior surface of the anterior or lateral wall; and
a second anchor that is deliverable percutaneously through the lumen of the first catheter to a position adjacent the perforation in the septum within the right ventricle; and
a tension member that operably couples the first anchor and the second anchor and that is configured to draw the septum and anterior or lateral wall toward one another via tension that is applied between the first anchor and the second anchor.

Abstract
Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.

9. A system for treating a heart of a patient comprising:
-
a catheter that is configured so that a distal end of the catheter that is advanceable percutaneously through an atrium of the heart and into a first chamber of the heart, the catheter being further configured so that the distal end of the catheter is positionable adjacent a first wall of the heart; an elongate body that is disposed within a lumen of the catheter and that is advanceable from the distal end of the catheter to perforate dysfunctional tissue of the first wall of the heart; a guidewire that is disposed within the lumen of the catheter and that is advanceable from the distal end of the catheter through the first wall so that a distal end of the guidewire is positioned within a second chamber of the heart, the catheter being configured so that the distal end of the catheter is advanceable over the guidewire, through the first wall, and into the second chamber of the heart, the elongate body being advanceable from the distal end of the catheter within the second chamber to perforate dysfunctional tissue of a second wall of the heart, and the guidewire being advanceable from the distal end of the catheter through the second wall so that the distal end of the guidewire is positioned external to the heart; a first anchor that is deliverable, via the catheter, to a position adjacent the second wall of the heart; a second anchor that is deliverable, via the catheter, to a position adjacent the first wall of the heart; and a tension member that operably couples the first anchor and the second anchor and that is configured to draw the first wall and the second wall toward one another via tension that is applied between the first anchor and the second anchor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
